Handling Process

A:
We can use DBWIN to solve problem ( to unlock deadlock module) if it is urgent :

1. Enable DBWIN on CLI

B-Vrsac-MAT-3su)%%dbwin enable
B-Vrsac-MAT-3(su)%%dbwin print 0x20 1

2. Get the PIDs in state P and release them
use "dbwin send 0x20 3" to get the problematic PID, for example:

B-Vrsac-MAT-3(su)%%dbwin send 0x20 3
{ |para2<0x...><0x0,0xffffffff> }:

Command:
dbwin send 0x20 3

[08:41:58.520]Send cmd to module 0x20.Cmd:0x3,SubCmd:0x0,Para1:0x0,Para2:0x0
[08:41:58.530] -?T: 0xae -P ////// PID is 0xae

Use following commands to release PID 0xae:

B-Vrsac-MAT-3(su)%%dbwin send 0x20 4 0xae
B-Vrsac-MAT-3su)%%dbwin send 0x20 5 0xae

3. Disable dbwin

B-Vrsac-MAT-3(su)%%dbwin print 0x20 0
B-Vrsac-MAT-3(su)%%dbwin disable

4. Test

B-Vrsac-MAT-3(config)#display vlan all
