• ASE errorlog shows Error 701 for several processes:
  
  Error: 701, Severity: 17, State: 3
  There is not enough procedure cache to run this procedure, trigger, or SQL batch. Retry later, or ask your SA to reconfigure ASE with more procedure cache.

• One of the processes hitting error 701 then fails with an "infected with signal 11" in the module curs_close:
  
  Current process (0x93004a) infected with signal 11 (SIGSEGV)
  Address 0x0x0000000002046bcc (curs_close+0x1cc) ...

• While handling the signal 11, a fatal exception is reported, which may cause ASE to go down:
  
  FATAL UNHANDLED EXCEPTION: signal 1047607760 hit while handling a previously hit signal. The server cannot continue and will shut down.

• The stack trace for the signal 11 includes functions:
