ERST Error code

ERST results when an event notification was cancelled due to a reset of the interface.

An ibwait call pending in the driver returns ERST in the following situations:

• Another thread in the same process calls ibonl using the same unit descriptor as ibwait.
• Another thread or another process issues a board-level ibonl 1.

An ibnotify Callback may be invoked with ERST in the following situations:

• Another process issues a board-level ibonl 1.

Solutions

Do not call ibonl with ibwait calls still pending in the driver.

Prevent other applications from calling ibonl by locking the interface with iblck.
