Error message in log - CMP persist message

Florent, do any of the iRules have any commands related to persistence at all?

We do have this.

 

We host a 2010 Microsoft Exchange solution.

 

Here is the irule:

 

 

when HTTP_REQUEST {

 

if {([HTTP::uri] == "/") || ([HTTP::uri] == "/exchange") || ([HTTP::uri] == "/exchange/") || ([HTTP::uri] starts_with "/exchweb/") } {

 

HTTP::uri /owa

 

}

 

 

switch -glob -- [string tolower [HTTP::path]] {

 

"/microsoft-server-activesync" {

 

 

pool Exchange_2010__owa_pool

 

COMPRESS::disable

 

CACHE::disable

 

return

 

}

 

"/owa*" {

 

Outlook Web Access

 

 

persist cookie insert

 

 

pool Exchange_2010__owa_pool

 

return

 

}

 

"/ecp*" {

 

Exchange Control Panel.

 

 

persist cookie insert

 

 

pool Exchange_2010__owa_pool

 

return

 

}

 

 

"/oab*" {

 

Offline Address Book.

 

pool Exchange_2010__owa_pool

 

return

 

}

 

"/autodiscover*" {

 

Autodiscover.

 

pool Exchange_2010__owa_pool

 

return

 

}

 

default {

 

 

pool Exchange_2010__owa_pool

 

}

 

}

 

}

 

when HTTP_RESPONSE {

 

if { [string tolower [HTTP::header values "WWW-Authenticate"]] contains "negotiate"} {

 

ONECONNECT::reuse disable

 

ONECONNECT::detach disable

 

this command disables NTLM conn pool for connections where OneConnect has been disabled

 

NTLM::disable

 

}

 

this command rechunks encoded responses

 

if {[HTTP::header exists "Transfer-Encoding"]} {

 

HTTP::payload rechunk

 

}

 

}

i do not see any information about that message (CMP persist message: persist data size ... exceeds maximum length 4096) in either internal (only where i can access) or external resource. if no one here knows, can you open a case and ask for its meaning?

Thanks for the response, i will try to open a case and keep you inform.

 

 

edit: Ticket was opened on friday, wait & see

 

Here is the first answer i got from the support:

 

 

"Thanks for the data.

 

This error might be related to persistence data length limitation. I will try to reproduce the issue here. "

 

 

I will keep you inform.

 

thanks Florent!

good thing the production doesn't seem to be impacted...

 

Here is the new answer:

 

"I could not reproduce the error message. I have escalated this case for further analysis.

 

I will let you know when I hear back from the escalation team."

 

i am able to reproduce the problem. i think your support engineer is correct. you are adding large size key to persistence table, aren't you? is it expected (large size key)? would it be possible to reduce its size (e.g. hashing, using unique part of it)?

Hi, sorry for the delay.

 

Where can i see if I use a large size key for the persistence ? Is-it in my I rules? If so i see nothing like that.

Where can i see if I use a large size key for the persistence ? Is-it in my I rules? If so i see nothing like that.you are using "persist uie" command in irule, aren't you? could it be the persist uie command argument?
