Status: Verified
FACT(s) (Environment):
Progress 9.1x
WebSpeed 3.1x
SYMPTOM(s):
WTA: WebWrite() failed during npp_send with error: size: sentbytes retrycount . (6404)
WTA: WebWrite() failed during npp_send with error: -70 size: 8232 sentbytes 0 retrycount 4. (6404)
Webspeed page does not return. Only a white screen is displayed.
Database hosted on a dual CPU machine.
Any access to the Database is slow.
Increasing the maxSrvrInstance or/and requestTimeout values does not help.
Increasing the CGI-timeout within WebServer does not help.
Setting the environment variable AGENT_RETRY_VAL=0 in the environment section for the WebSpeed broker does not help.
CAUSE:
The Database was not tuned properly for this dual CPU machine.
The requests from the agent were queuing up at the Database causing a high number of resource waits.
These requests were taking too long and eventually being timed out by the WebServer, resulting in error (6404).
FIX:
Set -spin to a value greater than 0.
