[Bug 713879] Re: byobu crashes on start 'pipe: too many open files'
I used byobu 4.37-0ubuntu1 in Ubuntu Server 11.10 64 bit. I left byobu running. But every few hours it will automatically close saying pipe: Too many open files y. Ulimit -n was 1024. I upgraded to 5.16-0ubuntu1~ppa5 and the problem still existed. I raised ulimit -n to 4096. Instead of crashing it will go into an infinite loop using 100% CPU. These were 2 backtraces from the infinite loop. #0 0x7f7ac5ad25f3 in select () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x004447bc in ?? () #2 0x00404e3f in ??

[Bug 713879] Re: byobu crashes on start 'pipe: too many open files'
Okay, I added a couple of ulimit checks to the byobu -v path. It costs a fork (0.01s) for each of the shell outs to ulimit, which shouldn't be necessary in the default code path. However, I can see this being useful if someone runs 'byobu -v'. Thanks for the information. Ping me if you guys find any other ulimit values/limits worth testing!

Interesting. On the machine I've tested it, the maximum number of open files (-n) was 1024, but the issue showed up anyway. What's more an issue, I guess, is the -u limit (max user processes) which is set at 24. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/713879 Title: byobu crashes on start 'pipe: too many open files' To manage notifications about this bug go to: https://bugs.launchpad.net/byobu/+bug/713879/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I added an entry to the manpage saying: +Byobu requires a suitable \fBulimit\fP(3) values to run. If you get an error at startup saying, 'pipe: too many open files', then check your ulimit -a values, as your open files or max user processes are too low.
