No request delivery notification has been received from LSAPI process group

[accassar]

Hello,

From time to time I get:

No request delivery notification has been received from LSAPI process group [-1], possible run away process.

Followed by:

Retry with new process group.

What does it mean?

I have tried the LSAPI_ACCEPT_NOTIFY=1 and =0 settings with no changes. Seems to happen in spurts.

Hello,

From time to time I get:

No request delivery notification has been received from LSAPI process group [-1], possible run away process.

...

the run away process mean there is php code issue that crashed LSPHP so that no request delivery notification gets sent. LSPHP parent has to spawn a new process to handle the request.

I'm not seeing any processes crash. How can I debug this?

look at the entries around the one you pointed in the error log and see which URL causes the problem. run the php manually with lsphp5 (/usr/local/lsws/fcgi-bin/lsphp5 /path/to/php_file) to see error.

After a day of running php inside of GDB, I could see there where far fewer crashes (say 5) then the number of these errors I have received.

I reapplied LSAPI_ACCEPT_NOTIFY=0 on the lsapi processes and restarted - it seemed to go away.

I also notice these errors when restarting lsws.
