[Serusers] ERROR: t_get_trans_ident: no transaction found - sr-users

8 Jun 2005


      Whenever I make a call I get these entries in the log....
Jun  7 17:56:29 ns2 ser[520]: WARNING: script writer didn't release
transaction
Jun  7 17:56:42 ns2 ser[522]: ERROR: t_get_trans_ident: no transaction found
Jun  7 17:56:42 ns2 ser[522]: assemble_msg: t_get_trans_ident failed
Jun  7 17:56:42 ns2 ser[522]: ERROR:tm:t_write_req: Error int assemble_msg
Jun  7 17:56:42 ns2 ser[522]: ERROR: t_reply: cannot send a t_reply to a
message for which no T-state has been established
If the user is online I get connected properly, if user is offline I get
connected to sems. So It seems to be working after all. But I had this
config running for three days then I got a lot of errors regarding t_newtran
and out of memory... and phones lost their registration.
Also does any have any idea where to put t_release() to avoid the first
WARNING message...
