M204.0956  Serious CRAM error​,​ thread halted: error code ​=​ errorCode

CRAM has encountered a serious error from which it cannot recover. The condition will force a snap and a restart of the user. Some errors result in a halted CRAM thread. All other threads remain unaffected.

System manager response: Determine the error. The possible error codes are:

Error code



Invalid CRAM function requested


CRAM ICB format error


CRAM user open had an invalid channel name or

CRAM read/write failed, channel not open


CRAM master open specified a channel name that was already open or

CRAM read/write failed because other task died


All CRAM threads in use or

CRAM read/write failed with an unexpected command


CRAM master open subtasks failed or

CRAM read/write failed because of a bad internal user number


CRAM function failed because there was not enough system queue area (SQA) or common storage area (CSA)

The IFAMSTAT command may be used to display status information on all IFAM users. If the thread is halted, you may need to issue IFAMFORCE or IFAMDRAIN commands.

If the problem persists, contact Technical Support and have the following information available:

  • Snap
  • Audit trail
