There is an AIX subforum here - post AIX problems there next time please^^
How did you notice it is locked up? Can you please post a vmstat -vs? An iostat of the disk(s) on which the problematic filesystems is placed on could help too.
Edit: Are you using AIO? If yes, "lsattr -El aio0" and "ps aux| grep aioserver" and iostat with -AQ to check aio queues maybe, please, ty
What kind of application is causing that traffic?

local-filesystems(7) Miscellaneous Information Manual local-filesystems(7) NAME
local-filesystems - event signalling that local filesystems have been mounted SYNOPSIS
local-filesystems [ENV]... DESCRIPTION
The local-filesystems event is generated by the mountall(8) daemon after it has mounted all local filesystems listed in fstab(5). moun- tall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with other activity. This event is typically used by services that must be started in order for remote filesystems, if any, to be activated. Remember that some users may not consider it wrong to place /usr on a remote filesystem. For most normal services the filesystem(7) event is sufficient. This event will never occur before the virtual-filesystems(7) event. EXAMPLE
A service that wishes to be running once local filesystems are mounted might use: start on local-filesystems SEE ALSO
