[OpenSIPS-Users] OpenSips 1.4.2 - ERROR:core:parse_via: invalid port

[joel garcia]

Version: OpenSip 1.4.2 
OS: CentOS release 5 (Final)  x64

Under decent load, we're seeing more than a few parsing exceptions
where it appears as though some of the memory is getting overrun 
 
Examples are 
 
Feb 28 08:03:17 sip101 /usr/local/sbin/opensips[11614]:
ERROR:core:parse_via: invalid port number
<5060branch=z9hG4bK49a93615-0234-0065adf8-8162901a-4330cddf>

Since the ; has been replaced with another character, the parsing tries
to cast the string to an unsigned short, and hence the error. 
 
The via appears to come in correctly, but something is corrupting it 
 
Via: SIP/2.0/UDP XX.XXX.XX.XXX:5060;branch=z9hG4bK49a93615-0234-0065adf8-8162901a-4330cddf 
 
More problematically, we're seeing the same corruption take place in our responses to our media server, which is causing the sip parser on our media server to crash. 
 
Any thoughts or ideas would be appreciated? Would upgrading to 1.4.3 or 1.4.4 resolve the issue? 
 
Thanks in advance.
Joel

p.s. more errors are attached.
