Thanks again for rour feedbak.<br>

Unfortunately that's not the case. I'm attaching an example with the same<br>
Via that works perfectly.<br>
<br>
<br>
<br>
Also, opensips works perfectly all day and only stops sending some OKs<br>
during peak hour.<br>

Do you have any other idea?<br>

Hi Diego,<br>
<br>
<br>
<br>
I looked at your pcap file and I see that your second via has this:<br>
<br>
<a rel="nofollow" target="_blank" href="http://bc01.mbcscr4.mss.ims.tigo.com.gt/">BC01.MBCSCR4.MSS.IMS.TIGO.COM.GT</a><br>
<br>
<br>
<br>
Is this a valid address? Maybe opensips can not resolve it so it ignores the<br>
via. Have you tried adding it to /etc/hosts.<br>
<br>
<br>
<br>
Compare a good 200OK with one of these and see if there is any difference.<br>
<br>
<br>
<br>
Regards,<br>
<br>

Hi Diego,<br>
<br>
<br>
<br>
Have you tried disabling the logging? That's usually the problem. Syslog<br>
slows down opensips.<br>
<br>
<br>
<br>
Also in /etc/syslog.conf as '-' before the file path to make it<br>
asynchronous.<br>
<br>
<br>
<br>

Hello,<br>
<br>
I'm using opensips to forward incoming INVITEs to a set of 8 applications.<br>
I'm using dispatcher module to achieve this.<br>
During peak hour, opensips receives about 350 INVITEs per second, during<br>
this period about 30 OK responses per second my application sends correctly<br>
aren't forwarded by opensips.<br>
<br>
I've recompiled opensips so it can use more memory by modifing the config.h<br>
file:<br>
<br>
#define PKG_MEM_POOL_SIZE 10*1024*1024 /*!< Used only if PKG_MALLOC<br>
is defined*/<br>
#define SHM_MEM_SIZE 320 /*!< Used if SH_MEM is<br>
defined*/<br>
<br>
<br>
The incoming INVITEs come from UDP and TCP.<br>
<br>
<br>
For each of the OK responses that aren't forwarded this entry appears in the<br>
messages file:<br>
<br>
usr/local/sbin/opensips[24554]: ERROR:core:forward_reply: no 2nd via found<br>
in reply<br>
<br>
According to my research on the web this message means that the OK only has<br>
one Via header, however this is not the case and the capture attached (made<br>
on server which runs opensips) shows it.<br>
<br>
I've also tried to increase the log level, but it made opensips to work slow<br>
even in low traffic hours.<br>
<br>
<br>
I run some test in my lab and opensips worked perfectly even under more than<br>
350 INVITES per second, this problem only occurs in production<br>
<br>
I really don't know what else to do.<br>
Could you help me to fix this issue or at least move on with the<br>
investigation?<br>
<br>
Thanks<br>
Diego<br>
