openlitespeed lsphp processes not dying

[lonea]

Switched the openlitespeed and it seems like the PHP processes are not dying properly.

When I check top and the lsphp processes is just piling up to the Entry process limit.

Adjusted the max_execution_time to 10 seconds but the processes are still there.

For example,

strace -p 2507378
strace: Process 2507378 attached
select(4, [3], NULL, NULL, {0, 540249}) = 0 (Timeout)
getppid() = 2387341

Any idea?

They had a bug in LSAPI 7.4.3, please make sure it's 7.5 or higher:

lsphp -i | grep -i litespeed

Just did a full build on the server and issue seems to be still happening.

Any other update I should be running? Already did a yum update -y

lsphp -i | grep -i litespeed

Hm.. it's 7.5, maybe another bug there? I'd suggest trying their support channel in Slack or just mailing them on the issue. Is this OpenLiteSpeed 1.5.3?

 

[lonea]

It was 1.4.8, just updated to 1.5.3. Same issue it seems.

 

[smtalk]

You may give lsapi 7.4.2 or older a try then to see if that changes anything.

 

[lonea]

Is there a way to downgrade using CustomBuild 2.0 plugin or I have to manually do it via cli?

We always use the latest version, but you may edit "build" script, find:

PHP_LSAPI_VER="`curl -k -L --silent --fail http://update.litespeedtech.com/ws/latest.php | grep 'PHP-LSAPI' | cut -d= -f2`"

Replace with, for example, old 7.2:

PHP_LSAPI_VER=7.2

Run "./build php n" (do not do "./build update" as it'd overwrite your build script) After this "lsphp -i | grep -i litespeed" should show 7.2 as the version.

Same issue after downgrading.

I'm just gonna stay with Apache + suphp until this is resolved.
