Litespeed stoped responding today and I had to restart it. Some virtual hosts were still responding (ones with their own IP), others not.

In my error_log file I had this at the moment it stoped responding :

Code: 
*** glibc detected *** litespeed (lshttpd): double free or corruption (out): 0x00000000044a39c0 ***
2013-11-27 12:30:08.070 [STDERR] *** glibc detected *** litespeed (lshttpd): corrupted double-linked list: 0x00000000014df440 ***
What is this ?

Thanks

if you can get core dump, then it'll help to identify the issue.

#yum install gdb
#ulimit -c unlimited
#stop / start lsws

see if you can capture a core dump if litespeed process when the issue come again.

Hello,

I've just had the same crash.

Here is the error message :

2013-12-05 18:19:25.024 [STDERR] *** glibc detected *** litespeed (lshttpd): munmap_chunk(): invalid pointer: 0x00000000048c4680 ***
2013-12-05 18:19:25.024 [STDERR] *** glibc detected *** litespeed (lshttpd): corrupted double-linked list: 0x0000000002fff1f0 ***
Click to expand...
gdb was installed some time ago.

I've just run ulimit -c unlimited but I don't belive this is related to getting a coredump.

Where would the coredump be created ? What option do I need to set in litespeed to allow coredumps ?

Should I force an update of litespeed, have there been any fixes recently without changing the number that could fix this issue ?

Thanks,

It doesn't happen very often and so far hasn't happened during the night so I haven't been woken up yet by it… !

Last time it happend I removed Cloudlinux's process limits to only leave entry limits as in Worker mode each user get's one entry process so I have enabled forked process limits. But I disabled this the previous time and as it happend again it's sign that it's not a process limit, I was getting 503 restarts when a user hit his process limit and disableling the CL process limits fixed this.

I've forced litespeed to reinstall and am recompiling PHP to get the latest LSAPI version in case this was updated too without changing the numbers.

It would be much easier if there could be some form of subnumbers to know if a newer version was available or not, (a build number and a changelog per build number or something) maybe just in your documentation so that users could see what issues/bugs were fixed and have an idea if an update could fix their issue.

The same type of issue happening on my server.

the server is not loading sites and Openlitespeed is showing running. tried to restart the webservice(lsws) but same issue after that.
So finally I had to restart the server and its working fine
While checking the server log I found the below error occurred both times when the site was not accessible.
2022-11-07 18:35:15.961 [STDERR] double free or corruption (!prev)
Here is the server detail:
OS: ubuntu 18.04
CP Version: 2.1.2
Openlitespeed: 1.7.15
Any suggestion Please?
