Re: Healthchecking problem on Alteons

Hi,

10 mins is the default timeout of session entry, i think you must increase
this value.

Command : /cfg/slb/real <server number>/tmout

eg : if you have 3 real servers , you need to define one tmout for each real
server :
 
/cfg/slb/real 1/tmout 15
/cfg/slb/real 2/tmout 15
/cfg/slb/real 3/tmout 15

regards,

MATMANE.
