SQL Server 2008 R2 reindex job reorganise getting stuck I am currently experiencing this job getting stuck in my nightly maintenance solution -

ALTER INDEX [PK_ThirdPartySettleCalled] ON [evo_archive].[dbo].[ThirdPartySettleCalled]
 REORGANIZE WITH (LOB_COMPACTION = ON)


a full reindex of the table works. 

but I'm using Ola Hallengren's awesome solution as I do on a number of sites that need maintenance solutions. http://ola.hallengren.com/Documentation.html and the job gets stuck in the middle of the night. 

I've tested it as a single statement from within ssms with the same result, without an error I'm a little short of ideas.

Anyone experienced this issue before ?

No blocking, 

the table is circa 300 million rows, 

basically I say 'stuck' because no other processes are running in SQL server, and its been reorganising for hours with no error. 

It is in the same state with 25% fragmentation or virutually 0% (tested after a full rebuild of the index)
Resolved

The problem was we had a rogue cron job (unix job) related to our web servers that was using an incorrect login, 

eventually it took up all 8 CPU’s so the reindex job was simply waiting for some CPU to become available before it could continue (this is why the job failed to timeout)
