Error description

  • If we start cdr either by bouncing the engine or with a cdr
start we will lock each row in the trg_send_srep and
trg_send_stxn tables. This can cause excessive locks as well as
problems associated with lock table allocation if there is not
enough memory. The following is a stack trace seen when the
engine was being brought online - and in this case SHMTOTAL had
been reached which results in an assert failure each time we
cannot get a lock:
