The number of thread at Os level is always grater than teh value reportetd in monThread table

[andrea_sala]

Hi there

• As many of you i'm tring to define the right number of thread for our ASE plaing with "network polling mode","number of disk task", "number of network task" e thread pool but at the end at os level i get a different value than expected.

In our develop environment I try to configure an ASE with the few number of thread as possible.

• OS: RedHat 8.10 x86_64, HW TYPE: VMware7,1, MEMORY (MB): 80015, CPU #: 8
• ASE "16.0 SP04 PL05" with
• kernel mode = threaded
• network polling mode = inline
• number of network task = 1
• number of disk task = 1
• syb_blocking_pool = 1
• syb_default_pool = 1
• syb_system_pool = 2 as a result of number of task config

The result of "select * from monThread" is only 4 rows as aspected

but the linux top -H -p<dataserer pid> reports 10 threads

the dataserver pid + 4 pid as monThread reports + 5 extra thread

Could you explain me the meaning of those extra 5 thread?

Thanks in advance 

Andrea
