Hello,
Sorry, next try with posting this message. Attempts with attachment failed due to message
size.
We are running OpenSER in a pilot project and unfortunately have some stability problems.
Any help or hints are appreciated.
Project information
OpenSER is used in a pilot project with
* Appr. 5000 subscriber accounts
* Appr. 1200 simultaneously registered users
* Signalling encrypted with TLS
* Media data encrypted with SRTP
* Clients: softphones and hardphones
* Re-registration time for clients: 3600 sec
OpenSER configuration
· Works as stateful SIP Proxy
1 mySQL database
2 Version 1.3.4.-TLS
3 Tcp_children: 100 --> is it recommended to increase this number?
4 Udp_children: 20
5 Tcp_connection_timeout: 3600
6 Shared memory:
· -m 512 when error occurred
1 Now set to 1024
Problems
* Shared memory consumption
Shared memory usage is permanently increasing (about 50 MB per day)
Application already crashed twice
First messages were, these, repeated thousands of times (5915 times):
Jun 17 08:54:52 si-.... /usr/local/sbin/openser[13921]: ERROR:core:tcpconn_new: shared
memory allocation failure
Jun 17 08:54:52 si-... /usr/local/sbin/openser[13921]: ERROR:core:handle_new_connect:
tcpconn_new failed, closing socket
And a few of these also (7613 times):
Jun 17 08:57:24 si-... /usr/local/sbin/openser[13880]: ERROR:core:tls_accept: some error
in SSL:
Jun 17 08:57:24 si-... /usr/local/sbin/openser[13880]: ERROR:core:tls_print_errstack:
error:1409C041:SSL routines:SSL3_SETUP_BUFFERS:malloc failure
* TCP errors, lost SIP messages
Examples from error messages:
14.100 times in log file from 17.06.09

Appears at least 20 000 times; and in the day of the last shared memory errors, it was
225.794 times in the log file (note that the number in parenthesis is usually 1 or 2, but
on that day it has reached 6):
Jun 17 09:01:27 si-.... /usr/local/sbin/openser[13921]: WARNING:core:send2child: no free

Jun 17 09:01:27 si-... /usr/local/sbin/openser[13921]: WARNING:core:send2child: no free
tcp receiver, connection passed to the leastbusy one (5)
* Certificate validation problems
TCP traffic is currently significantly increased by some ( appr. 70) clients which failed
to validate the TLS certificate. Registration is repeated every 5 sec.
Circa 30 thousand per day (on that day, it was 37.162 times in log)
