Hi,<br><br>I am having random Linux Kernel crash problems while running FreeSWITCH as Skype to/from SIP gateway on one of our production servers. This machine is running CentOS 5.2, Kernel version 2.6.18-92.1.22.el5.centos.plusPAE with FS svn revision number 13754.<br>
<br>At time of Kernel crash i could find following crash messages which point to some source code file in FS source tree.<br><br> --------------------- Kernel Begin ------------------------<br><br><br> 3 Time(s): =======================<br>
3 Time(s): [<c0404eff>] syscall_call+0x7/0xb<br> 3 Time(s): [<c043ed22>] sys_delete_module+0x192/0x1b8<br> 3 Time(s): [<c0449011>] audit_syscall_entry+0x14b/0x17d<br> 3 Time(s): [<c049f4fe>] remove_proc_entry+0x139/0x18c<br>
3 Time(s): [<f8d96281>] alsa_sound_exit+0xa/0x30 [snd]<br> 3 Time(s): [<f8d96304>] snd_info_done+0x46/0x49 [snd]<br> 3 Time(s): BUG: warning at fs/proc/generic.c:732/remove_proc_entry() (Not tainted)<br> 1 Time(s): snd-malloc: Memory leak? pages not freed = 1<br>
<br> ---------------------- Kernel End -------------------------<br><br>While the problem seems to arise from ALSA kernel module but it blames FS file fs/proc/generic.c:732 for this. The only FS module that is using ALSA is mod_skypiax but as far as i remember that module is using FS internal routines to allocate and de-allocate sound driver services for Skype client.<br>
<br clear="all">Please suggest a solution.<br><br>Thank you.<br><br><br>-- <br>Muhammad Shahzad<br>-----------------------------------<br>CISCO Rich Media Communication Specialist (CRMCS)<br>CISCO Certified Network Associate (CCNA)<br>
