There are two types of panics which can occur during quotactl calls, a panic with the panic string "lock_terminate: lock held", and a kernel memory fault in dyn_hash_remove.
Partial stack traces for both types follow.

HP Tru64 UNIX 5.1B-2 ERP Kit

The HP Tru64 UNIX V5.1B-2 ERP Kit contains the fix for a newly uncovered KMF in access_invalidate problem. The two typical stack traces for the KMF in access_invalidate are:

0 stop_secondary_cpu 1 panic 2 event_timeout 3 printf 4 panic 5 trap 6 _XentMM 7 access_invalidate 8 bfs_dealloc 9 dmn_dealloc 10 bs_bfdmn_deactivate 11 fs_fset_get_info 12 msfs_real_syscall 13 msfs_syscall 14 syscall 15 _Xsyscall

0 boot 1 panic 2 trap 3 _XentMM 4 access_invalidate 5 bfs_dealloc 6 dmn_dealloc 7 bs_bfdmn_deactivate 8 msfs_unmount 9 cfs_unmount 10 dounmount 11 cfs_do_unmount_accept 12 cms_handle_send_msg 13 cms_kgs_callback_thread

HP Tru64 UNIX 5.1B-3 ERP Kit

The HP Tru64 UNIX V5.1B-3 ERP Kit combines the fix for a newly uncovered KMF in access_invalidate problem with fixes previously announced in EA c00640881 (Potential AdvFS Hangs).
The two typical stack traces for the KMF in access_invalidate are:

0 stop_secondary_cpu 1 panic 2 event_timeout 3 printf 4 panic 5 trap 6 _XentMM 7 access_invalidate 8 bfs_dealloc 9 dmn_dealloc 10 bs_bfdmn_deactivate 11 fs_fset_get_info 12 msfs_real_syscall 13 msfs_syscall 14 syscall 15 _Xsyscall

0 boot 1 panic 2 trap 3 _XentMM 4 access_invalidate 5 bfs_dealloc 6 dmn_dealloc 7 bs_bfdmn_deactivate 8 msfs_unmount 9 cfs_unmount 10 dounmount 11 cfs_do_unmount_accept 12 cms_handle_send_msg 13 cms_kgs_callback_thread

This first type of hang could be seen by customers with an AdvFS clone mounted and a file is being extended using Direct I/O .
A forced crash during this type of hang produces the following stack trace.

0 thread_block
1 sleep_prim
2 mpsleep
3 insert_actRange_onto_list
4 cow_get_locks
5 bs_cow_pg
6 bs_cow
7 bs_pinpg_clone
8 bs_pinpg_ftx
9 copy_and_del_frag
10 fs_write_add_stg
11 fs_write
12 msfs_write
13 vn_pwrite
14 prwuio
15 pwrite
16 syscall
17 _Xsyscall

This second type of hang could be seen by customers with an AdvFS clone mounted and a file is being truncated using Direct I/O .
A forced crash during this type of hang produces the following stack trace.

0 thread_block
1 sleep_prim
2 mpsleep
3 insert_actRange_onto_list
4 fs_setattr
5 msfs_setattr
6 cfs_comm_setattr
7 cfscall_setattr
8 cfs_setattr
9 vn_open
10 copen
11 syscall
12 _Xsyscall

This third type of hang can be seen by customers running vfast or defragment on an AdvFS domain, if the system is in a cluster.
A forced crash during this type of hang may produce either of the following stack traces.

0 thread_block 1 sleep_prim 2 mpsleep 3 insert_actRange_onto_list 4 msfs_flush_and_invalidate 5 cfs_comm_open 6 cfscall_open 7 cfs_open 8 vn_open 9 copen 10 syscall 11 _Xsyscall

1 lock_write 2 cfs_condio_cc_excl_mode_enter 3 migrate_get_clu_locks 4 migrate_normal 5 mig_migrate 6 bs_migrate 7 ss_vd_migrate 8 ss_move_file 9 ss_work_thd_pool

This fourth type of hang hang can be seen by customers with an AdvFS clone mounted and at least two threads doing memory mapping to the same file.
A forced crash during this type of hang may produce either of the following stack traces
 

0 thread_block 1 lock_read 2 cow_get_locks 3 bs_cow_pg 4 bs_cow 5 bs_pinpg_clone 6 bs_pinpg_get 7 msfs_getpage 8 u_vp_fault 9 u_map_fault 10 vm_fault 11 trap 12 _XentMM

0 thread_block 1 lock_write 2 msfs_mmap 3 smmap 4 syscall 5 _Xsyscall
