Abstract
OSP-THREADS-INCORROUT UNEXPECTED MCH3601 OR MCH0601 MAY RESULT
ON A SYSTEM USING 4096 SECTORED UNITS.
Error Description
On a system using 4096 sectored units, unexpected MSGMCH3601 and
MSGMCH0601 may occur. This may result in unexpected
behavior from IBM HTTP Apache servers and cause the server to
stop responding to requests.
The symptom is not limited to HTTP.
Failures can include damaged journal receivers, MSGMCH0601,
MSGMCH3601, heap errors, HTTP server failures, jobs not
ending, etc. There could be other storage related errors as
well.
Here's how to tell if you have a '4096' type drive.
the drive type is either D840 or specifically 6B4E-050.
a) WRKDSKSTS OUTPUT(*PRINT) can be used to verify that drive
type is D840, but will NOT show the model for 6B4E. Use
DSPHDWRSC to confirm 6B4E-050.
b) DSPHDWRSC TYPE(*STG) OUTPUT(*PRINT) can be used to verify
6B4E-050 device type and model.
