Description Frederico Gendorf 2006-03-11 14:39:39 UTC
HI, after upgraded from 3.0.20X to 3.0.21X some smbd process go in loop and de CPU utilization increase linearly (see mrtg graphic).
before this upgrade de CPU utilization was minor who 25% and the strange is it only happens with one smbd process with random users.
whats going on?
thanks for regards!

MRTG cpu utilization, the red X represent a manual kill -9 in a process smbd

Can you attach to the process with gdb and give us a stack backtrace of where it is when it's using all the CPU please.

Comment 3 Frederico Gendorf 2006-03-11 19:08:52 UTC
Hi Jeremy, see the top description off the process that is overload now, see the CPU TIME and memory Resident size! and this increase linearly.
11855 kruger    16   0   48460  38m  2044 R 28.2  1.9    37:02.83 smbd
the stack backtrace of this process return this:
(gdb) where
#0  0x00111402 in __kernel_vsyscall ()
#1  0x007081ed in ___newselect_nocancel () from /lib/libc.so.6
#2  0x00d5feaa in sys_select () from /usr/sbin/smbd
#3  0x00c1222d in add_idle_event () from /usr/sbin/smbd
#4  0x00c13cc1 in smbd_process () from /usr/sbin/smbd
#5  0x00df13d5 in main () from /usr/sbin/smbd

I don´t undertand nothing about this, I wait that it helps you!
very thanks

Continue MRTG CPU utilization

the process that I have killed back to increase CPU utilization!

severity should be determined by the developers and not the reporter.

after 12 years we have to say now, please open a new bug if you experience any memory issues in the latest supported release branches.
