Bump Big Red banner at the top reads: "Not getting any help? Try reading....." Its like the forum is trying to make me furious... But seriously, Can we at least get some confirmation that a member of the bukkit team has glanced at this? It's a real issue for a lot of people... I'm now in the process of upgrading my server from 4GB to 8GB, Adding a new CPU and Switching to Solid State Drives... If i continue to get these read time outs, will you believe that its a problem? Bukkits twitter is filled with adding new stuff... You guys do great work... but can we fix what's broken first?
@Beldrama @Pulserock Please take a moment and fill out this short template, It will help us to have common factors between those who are crashing. if EVERY one was crashing it would be fixed by now...

Tried swapping out mcMMO, Levelcraft, Herochat, Multiverse, anything big...no differences. CPU level never above 20% (at the high points, regular 5-7%) and the memory never above 1.3gb when crashing so its not maxing out the server either.
Switched to a new server, Upgraded to 8gb of ram, and still get these errors, It does however take, much, much longer... down to only 1 reboot every 18 hours or so... still sucks... but now i can sleep.
@Tang: Ever considered automating reboots? I have to reboot every 2(!) hours because of short memory, but I automated it using http://forums.bukkit.org/threads/ad...4-a-cron-like-scheduling-system-733-803.6331/ and crontab. Yes, I'm on Linux. But still sucks...
I'm using an auto-restart plugin but the amount of time it takes to overflow the memory is unpredictable. Not to mention a 2hr restart might piss off a few ppl XD
It would be nice if the bug/issue could just be resolved, a crontab isn't a solution thats a work around. Thank you for the suggestion. I could run my server for weeks without a reboot before 1.7.2... Changed my startup script again, maybe it will help... Runs for about 10-20 hours now, 17-30 players on at most times of the day. may try a crontab for reboots every 10 hours, until this is resolved

Server will start out fine, then as the memory usage climbs, the console will begin displaying "[WARNING] Can't keep up! Did the system time change, or is the server overloaded?" This happens regardless of how many users are online. Once the memory usage reaches ~1.7GB the server will lock up and close itself; this normally happens after the server has been up for 2 hours.
I'm not sure how.. but I seem have to fixed it for me.. But the only things I remember doing were installing this plugin called RemoteToolKit. It's supposed to automatically bring your server back up after it crashes/receives a [SEVERE] warning. You can also configure it to automatically restart your server, auto-save, etc. But the other thing I did was uninstall BigBrother (it's supposed to have some bad memory leak right now), change my view-distance value in server.properties, and install a plugin called PerformanceTweeks. If anyone wants to try all these and see if it fixes your crashing problem, perhaps we could narrow it down to something..
Something I've noticed is when my server reaches 1.5GB, which is the amount I set in the startup bat, the lag starts to kick in and the console begins to receive the "[WARNING] Can't keep up! Did the system time change, or is the server overloaded?" error. Afterwards, this will continue until the memory usage hits about 1.7GB, in which the server will lock up and exit itself.
I had RemoteToolKit and PerformanceTweaks when this problem started for me. I'm going to trying removing BigBrother again (I had tried in the past). Also, what did you set your view-distance to?
I recently changed the view-distance up to 10 because anything less was causing monsters to de-spawn before they actually spawned. This was causing a server wide lack of mobs and animals.
This still isn't fixed for me, I've had to run without bukkit just to keep it from crashing every 3-4 hours. I tried turning down the view-distance and turning off BigBrother - neither worked. =(
This is so annoying. I'm forced to do a manual save about every 30 mins, because whenever I get the 'Read time out' error, the server locks up, crashes, and we undergo a rollback. This is a HUGE problem, and devs should really focus on this.
I thought I solved this problem by turning the view-distance down to 5 (in the server.properties), but I'm still getting 'read time out' errors and it eventually freezes and runs well over the max RAM I set. Anyone else have any luck?

Seems to do fine. RAM still fills up quickly, but the server didn't crash... yet. EDIT: Scratch that. Still crashes... EDIT 2: Rewind that... mcMMO crashed the server this time... It seems stable now. Hogs RAM like crazy (reaches 85% in no time) but stays there without crashes. Some lags occur when space is freed up however.
Same here please help i have 1.5 GB ram on the server I got a monster limiter plugin and did fix the crashes but now i just get read time out
old thread, but happens to me too... i think this is NOT a memory problem... my previous server has 2 gb of ram, and using bukkit build 2117... my current server is 3.5 gb of ram and using the 1.2.4 RB, these broken pipe errors occured switch back to the 2117 dev-build, never occur anymore :/
