The bug that I had we reproducible with only two client threads. It

Also, if you end up at a dead end and need the help of a FreeBSD

Re: mysql uses 99% cpu under freebsd 4.3
Hi, I have had some various similar things happen with other apps since upgrading to Fbsd4.2stable What I have learnt to do first before anything else is, reboot and load a SINGLE CPU compiled kernel to determine at what/where the bug may be. I had a/still occasionally get a constant waiting in KDE explorers but never get this during a single CPU test. Have had lots of mysql threads gobbling resources, too lazy to test, plus it was an early mysql (have not updated it from ports) since it has only done this twice since February (when we updated from 3.4 to 4.2). Probably doesn't help you all but I am watching this news thread eagerly.

I produced one about 9 months ago and gave it to Tim Smith. Had to
send him a CD-ROM, since it was rather large. But I can still reliably
kill a MySQL server running on FreeBSD 3.x and 4.x.
If there is renewed interest in fixing it, I can try to put one
together again.

Hi Sinisa!
Good to hear from you. Not having this problem yet, I am however
interested in the details of what you did find and what may be the
potential cure. I am asking as I would like a little more detail than
what would normally go in a log entry. IE how did the problem get
reproduced. Is it thought to be a bug in FreeBSD threads or a
difference in the thread lib or something else? And what the
attempted fix might be. (Maybe even a patch to try). I would be
happy to help test, resolve, duplicate any problems related to
FreeBSD. (This is important to us and anyone who runs production
FreeBSD servers!).

Hi Ken,
This seems to be a problem with threads on FreeBSD, although on which
side, yet remains to be seen.
It seems to appear that it is surfacing not just under heavy load, but
when there are many threads running. Many means more then 300 or 400.
I am not involved with this as I am poor BSD expert. Two of our
developers are working on the problem and will report their findings
to the general list as soon as they have something important to say.
As I am not involved with this, I truly am not able to shed more
light. One of our developers managed to pinpoint that most of CPU went
to some runaway thread. Causes of this are not known.
I would also like to say that this kind of problems are hardest to
crack and will require lots of effort. SIGSEGV's, on the other hand,
are very easy to fix in comparison.
Regards,
Sinisa

Re: mysql uses 99% cpu under freebsd 4.3
FYI, people experiencing this problem should try to make the mysqld as idle as possible (ie disconnect or idle the connections) and then run truss -p NNN (where NNN is the pid of the mysqld process) and post a typical chunk of the output. That would give valuable info to the mysql developers. Tim. On Tue, Apr 10, 2001 at 03:48:26PM +0300, Heikki Tuuri wrote: Hi!

I suspect the point is that many more threads simply makes the problem appear more often and thus be reproducible and thus more easily fixed. Tim.

Lots of disk I/O, and it looks like you're got a pretty small record length (20-byte reads? although the combo of lseek+read and pread on the same datafile is puzzling. Maybe it's a table with a couple of INT/CHAR columns and a BLOB column?). Does a "show processlist" say there's a query running? An interesting thing to see might be the output of a couple seconds of "iostat 1" and "vmstat 1", to see how much disk and syscall activity there is. -- Dan Nelson [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Can anyone of you guys come with a repeatable test case that will
always lead to the situation as described. Then we could try to fix
it.

Re: mysql uses 99% cpu under freebsd 4.3
Hi! People are reporting performance problems also from the FreeBSD port of Innobase. There seems to be a runaway thread which gets free sometimes and eats up 100 % of the CPU. It was not fixed with the latest patches to Innobase. I will try setting thread priorities in 3.23.37. That might help, but I guess the real reason is different. I will probably finish my work on 37 today and tomorrow I will try to repeat the problems on our FreeBSD computer.

Re: mysql uses 99% cpu under freebsd 4.3
I've seen what's probably the same thing under 4.2-STABLE. The poll() system call returns 1 but there's no corresponding file handle marked in the data structures that were passed to poll(). (It could be a mysqld bug if they're asking to poll() for certain kinds of events but then not checking for those events, but that seems unlikely. I've no time to check the code.) Tim.
