PHP suEXEC Max Conn: 500

this is too large and caused the error you reported.
the default is 10.

please back to 10, then increase it gradually, by step of 5 ot 10.

monitor
lsws web admin -> Actions -> Real-Time Stats
especially WaitQ column.
if it's always 0, or being non-0 very short time, then stop increasing "PHP suEXEC Max Conn"

When i decrease i saw that warn. My users are querying mysql per once in 15 seconds. and at least 500 images is being uploaded in one minute. I am curious if the issue is this. By the way theese queries is being querying from app (Android java).

please check if mysql is the bottle neck.
run
#mysqladmin processlist
help to tell some information.

looks like too many incoming requests -- like a DDOS.
you can try set
lsws web admin->Server->Security->Per Client Throttling
to limit request rate from single IP. see if it'll improve a bit.

from the real-time stats, one site has problem -- its WaitQ is 1,811

My process list is empty. Cpu is 0,20 the most. I can not understand. How can this happen.

 

[mert]

it looks the problem is lsphp5 taking too much time to complete a request. thus it queues up.
you can strace a lsphp5 process to find where it's blocked at.

 

[mert]

Do i have to do this? May it is about with this?

 

[NiteWave]

no need do it -- since it says lsphp5 already match with apache's.

 

[mert]

ok. Is This? By the way my website still unavable. I really need help. I sent you website adress via pm. Couldy you take a look?

 

[NiteWave]

it looks the issue has gone.
Can you let us know what's the problem ?
I suspect configuration issue, maybe the change of default ext app settings for lsphp5
