NimbostratusTCL Memory usage grow up
Dear,
we just use LTM around one week and I see have some problem on TCL memory usage part.
we see that TCL memory allocated and maximum GROW UP around 40M per day and now already around 300M. is it normal?
I am using 1500 LTM and 768M Memory only.
but, so strange that the total memory usage only around 210M and not grow up so much.
The TCL memory show is attached.
Regards
Simon.
Simon_Chan_1115Dear,
the following is the iRule that we are using:
when CLIENT_ACCEPTED {
set add_persist 1
}
when HTTP_RESPONSE {
if { [HTTP::cookie exists "JSESSIONID"] and $add_persist } {
persist add uie [HTTP::cookie "JSESSIONID"]
set add_persist 0
}
}
when HTTP_REQUEST {
if { [HTTP::cookie exists "JSESSIONID"] } {
persist uie [HTTP::cookie "JSESSIONID"]
} else {
set jsess [findstr [HTTP::uri] "jsessionid" 11 ";"]
if { $jsess != "" } {
persist uie $jsess
}
}
}
it is just simple iRule.
and today our web site down (cannot access) and I need to reboot the active and make failover.
Before failover, I cannot access the admin page and ssh to LTM. I can only use serial console to login and then type reboot in LTM.
do u have any idea on it? since it seems make our LTM memory leak.
Regards
Simon.
