[Samba] High cpu usage samba process

[Trenta sis]

Hi,

I have detected a high cpu usage for one process on samba, this process is 5745

# ps aux |grep samba |grep 5745
root      5745 80.1  8.9 759032 183220 ?       R    Mar21 2623:45

I suspect that high cpu usage is for some ldap task, but I'm not sure
and I like to know how to investigate what task is running to reduce
this cpu usage

during this high cpu usage, samba server perofrmacne is very low

Thanks
