We are experiencing an issue where Call manager logins shows, "database communication errors", Jabber users cannot log in, and a los of instabilities.
I opened a Cisco TAC to see which would be the case, and the engineer told me this.
Hi Juan , you are receiving the following errors:
11:54:00 (11977422) connection rejected - too many users, or invalid user name
11:54:00 Size of resident + virtual segments 93776KB + 988292KB > 1000000KB
11:54:00 total allowed by configuration parameter SHMTOTAL
11:54:57 create_tcb: cannot allocate memory
Could you please help me to see that memory?
* Se how much memory (exactly) is being consumed at any given time.
* See which is the service that is consuming that memory.
* Q. That memory (1000000KB is shared among several services? (Informix, tomcat, Bulk, CIMPC) ???
* Q. how does it work exactly?
* Q. Can it be configured/customizable (only is up to 1GB)?
* Q. Are there any given threshold numbers we are suppose not to bypass, for instance no more than X tomcat sessions.
* RTMT Helps?
* CLI commands.
That error is basically disrupting all the services because.
1. Users cannot login into call manager.
2. BULK tasks do not work.
3. Jabber users cannot log in.
Cisco said, "you have to restart A CIsco DB and Tomcat" I can do that, but it will help better to know if this issue is about to happen.
Juan.
