[OpenSER-Users] memory allocation issue

[Benko]

Hello!

I wanted to upgrade a server from 1.1.0 to 1.2.2 today but despite
extensive testing beforehand i have some trouble:
After starting with the new openser-binary, it didn't allow any
registrations and answered with "500 server error occured".
Logging said:

Sep 18 17:23:12 [/sbin/openser] ERROR: sip_msg_cloner: cannot allocate \
memory_ 
Sep 18 17:23:12 [/sbin/openser] ERROR: new_t: out of mem:_
Sep 18 17:23:12 [/sbin/openser] ERROR: t_newtran: new_t failed_Sep 18

and 

17:23:12 [/sbin/openser] ERROR: sip_msg_cloner: cannot allocate memory_
Sep 18 17:23:12 [/sbin/openser] ERROR: store_reply: can't alloc' clone \
memory_

after restarting it with "-m 128"(according to the faq) these errors are
gone, but it still doesn't accept registrations and prints:
Sep 18 17:24:16 [/sbin/openser] ERROR:tm:print_uac_request: no shmem_
Sep 18 17:24:16 [/sbin/openser] ERROR:tm:t_forward_nonack: failure to \
add branches_ 
Sep 18 17:24:16 [/sbin/openser] ERROR:tm:w_t_relay: t_forward_nonack \
failed_

[update] - after several restarts, the first error-messages appeared
again.

When i run the new version on port 5061(old production server 1.1.0 is
running parallel on port 5060) i can register with the new server(on
port 5061) without problems. 

I have the vague impression that the new instance can't free memory,
but why does it work when i run it on a different port? Any clues?
