Question about "glibc detected" (linux)
#1

Curious if this is normal:
(Usually i have SSH open 24/7 > Linux SSH Terminal pop this up while i was sleeping )

Code:

Hmm, that doesn't look normal to me..

In the time i have been working with SAMP servers, i haven't seen this error.

is the server running normally despite the error?

Yes, its running fine that i can see, but its not my server,
its 1 server on my VPS thats doing this. and its doing it on a daily basis.


edit:
noticed some of the plugins aren't loading and giving errors, but the server is runing fine as what i can see
and this is the only thing in server.logs with any issue:
Code:
[12:55:51]   Failed (libmysqlclient.so.15: cannot open shared object file: No such file or directory)

That error suggests that the machine does not have libmysqlclient.so.15 installed.

I would install that, and the error should go away.
