My users are getting intermittent 'blank screens' (truly blank, not diagnose connections) when the are trying to log in, this is the screen where they pick their environment and role.

I see the following in the apache access_log:

172.16.14.79 - - [01/Apr/2010:17:42:47 +0100] "GET /jde/E1Menu.maf?jdeowpBackButtonProtect=PROTECTED HTTP/1.1" 200 4324
172.16.14.79 - - [01/Apr/2010:17:42:47 +0100] "GET /jde/ResourceCanonicalsJS.mafService?e1.state=maximized&e1.mode=view&e1.namespace=&e1.service=ResourceCanonicalsJS&RENDER_MAFLET=E1Menu HTTP/1.1" 200 2955
172.16.160.158 - - [01/Apr/2010:17:42:51 +0100] "POST /jde/E1Menu.maf HTTP/1.1" 302 354
172.16.160.158 - - [01/Apr/2010:17:42:51 +0100] "GET /jde/E1Menu.maf?jdeowpBackButtonProtect=PROTECTED HTTP/1.1" 500 365
172.16.160.8 - - [01/Apr/2010:17:42:56 +0100] "GET /jde/owhtml HTTP/1.1" 301 5

Note IP address 172.16.14.79 does a post and gets the "GET /jde/E1Menu.maf?jdeowpBackButtonProtect=PROTECTED HTTP/1.1" and succeeds (200) and the ip address 172.16.160.158 4 seconds later fails with a 500.

Any ideas where I should look would be very much appreciated.

Thanks BOK,

I think this might help another issue I'm having. What I think was happening in our case was garbage collection was taking too long.

I changed the memory size from 1024M to 768M for the OAS instance and it seems to be solving our issue.

Only time will tell of course.

Agree that several small (768) JVM's are better at garbage collection than one large JVM (1024). Have you looked into disabling garbage collection altogether?
 
BOK,

I didn't even know that was possible. Can you point me at a doc? I know I can google it, but if you have it on hand I'd appreciate it.

I'll have to look around my notes, the concept is something we tossed around with the guys in Denver a few years back and it made perfect sense...I just don't remember why.
