Hello,
I have (AGAIN!) a very common issue with Classic ASP sites and IIS 7.5 Application Pool stucks... i have read so many articles about that and i really wonder why Microsoft have not developed any fix-update yet!
I am talking about very offen situations that for some unknown reason, IIS Application Pool hungs and most classic ASP sites do not load (loading forever) and then i have to recycle application pool to make all work.
My Setup is:
Dedicated WIndows 2008 R2 64Bit Server
IIS 7.5
Plesk Panel, and full RDP access
1 application pool containing 170 websites , most of them are classic ASP websites.
EVerything was working normal untill i decided to do windows updates (i had to do over 100 security updates by Microsoft). All updates were done without any problem. But after that i face this issue with app pool stuck AGAIN!! It is very annoying.
I tried to isolate 2-3 Classic ASP websites to dedicated app pools, and i set a Failed Request Tracing rule for every one of them. What i get on every one of them are:
LOG_FILE_MAX_SIZE_TRUNCATE (warning)
and also in Module Notification a NO_END module:
ModuleName | IsapiModule |
---|---|
Notification | 128 |
fIsPostNotification | false |
Notification | EXECUTE_REQUEST_HANDLER |
I haven't change anything in my code and all websites were working fine untill the windows updates!! Please tell me what to do because i have very serious problem with most of my customer complaining that their websites are not loading....
thank u very much!!
EDIT: I have just noticed something in memory. When i recycle App Pool, it is consuming over 20-30 mbytes of Ram. After , say 3 hours, it is increased to over 100 MBytes of ram ( for a single website). What is going on?? What would be the reason for such memory increase during time??
Also when App Pool is stuck and i try to recycle app pool i get this error on event viewer: "A process serving application pool 'liolios.gr(domain)(2.0)(pool)' exceeded time limits during shut down. The process id was '3456'. "
