MVPBigIP ASM Problems with FileUploads with SOAP
Hi there,
actually my ASM Policy is blocking a file upload for one application with the error message:
HTTP protocol compliance failed
Chunks number exceeds request chunks limit: 1000
I raised the chunks limit blindly from 1000 to 1500 with no success. Where I can see the actually number of chunks without capturing the traffic? After disabling the funktion "Unparsable request content" Upload went through without a problem. But from the notice I would stick this on?
Note that disabling this check can result in losing many enforcement features in the ASM.Sametime I get the following syslogs:
ASM out of memory error: event code X242 Exceeded maximum memory assigned for XML/JSON processing
Cannot allocate 27415074 more bytes for XML parser. current memory size 837505174 (in bytes)As you can see I raised the available memory for XML request from 450MB (default) to nearly the double.

Hi HarunT,
yep checked that already. It feels that the additinal required memory is raising over time. So I changed the value already to nearly the double and everytime the message appears it wants about 20-30mb more and raising.

What is the size of the file in question?
- P_Kueppers
Two files with bearly under 10MB. XML Profile and every other setting limits I found are at least high enough or any.
- AubreyKingF5
Very odd. The error indicates that it's trying to handle ~840 Meg. ASM logs show anything?
- P_Kueppers
Maybe anyone got ad idea?
It happens 2-3times a day and we are already at 1GB but keep getting
BD_XML|ERR |Sep 20 12:11:39.672|26884|xml_validation.cpp:0244|Cannot allocate 22474662 more bytes for XML parser. current memory size 1002457583 (in bytes) Hey P_Kueppers - are you still seeing the same issue, or were you able to resolve it?
- P_Kueppers
Nope. Same issue every few days and still on 14.x but I cant imagine that this is a bug and will be fixed with 15.x
I think the messages doesnt come from the application I suspect rather a other one. How can I track this? Some fancy iRule to log this big XML requests? I can imagine that this is coming from a total different application where Im not informed about xml/soap requests.
Tagging AubreyKingF5 again for his technical expertise...
