Cisco UC520 Upgrade


i have a UC520، and it show the below error:

"Oct  6 09:47:31.695: %SCHED-2-EDISMSCRIT: Critical/high priority process VTSP may not dismiss. -Process= "VTSP", ipl= 0, pid= 236,  -Traceback= 0x80E728F8 0x8209D2D8 0x80E5ACA0 0x80E8BFD0 0x80E8A9E8 0x80E8BAF0 0x8213A018 0x8213A278 0x8213A628 0x8213131C 0x82132600 0x80B47F24 0x80851530 0x80859A04 0x82DB8848 0x82DB8FB0"

And i was read the error related to bug, and the upgrade is the solution of this bug, so we will go into upgrade, does i need to upgrade the whole package like below link :

or i can just upgrade the IOS? and if i will upgrade the IOS deos it affect the system Cisco Unity Express.

The Second question,if i need to upgrade the whole package,  does the upgrade need license?

sh license feature

IOS update does not affect Unity Express, and does not affect license.

So if i upgrade to the "uc500-advipservicesk9-mz.151-4.M6" IOS this will upgrade the CME, and it may solve this Error.

but if i will upgrade the whole UC500 does this require license?
