PTF RO93603 has been applied to prevent problems when using the NOPACK option, and now this message sometimes appears:
SYBINP808L - TASK HANG DETECTED, ATTEMPTING RECOVERY
Is this to be expected ?
Yes, this message was added with the ptf so that we know for sure that the task hang situation had been hit and corrected.
It is documented in docops under SYB808 :
hh:mm:ss.xx - TASK HANG DETECTED, ATTEMPTING RECOVERY
A HiDRO task is deadlocked because both its input process and output process are out of buffer space. Therefore, the task cannot proceed. To break the deadlock and to prevent an eventual EC100 abend, HiDRO forces the output process to write a short data block to free those buffers so the task can continue.
