TMD5 - can't open in read mode - does this matter?

ROOT

Hi,
Sometimes when I’m running I see the following error. Does it matter?

23:02:46 24876 Wrk-0.0 | Info in <TXProofServ::HandleCache>: loading macro junk_macro_parsettree_CollectionTree.C+ ... 23:02:46 24876 Wrk-0.0 | Info in <TUnixSystem::ACLiC>: creating shared library /phys/groups/tev/scratch4/users/proofbox/gwatts/session-tev11-1325746963-30943/worker-0.0-tev01-1325746964-24876/./junk_macro_parsettree_Coll ectionTree_C.so 23:02:46 24876 Wrk-0.0 | Error in <TMD5::FileChecksum>: cannot open /phys/groups/tev/scratch4/users/proofbox/gwatts/cache/junk_macro_parsettree_CollectionTree_C.d in read mode

The only time I ever see this is if I’m TProof::Load’ng a simple file comiled c++ (in this case it is a 1 line file). Should this worry me? Is it do to some mis-config of our proof cluster? Or a race condition of some sort?

I’m running ROOT 5.30.01 on the client and server, and it is SLC4 on the server.

Hi,

I’ve never seen this.
It looks to me that the problem appears while saving things to the cache, so the effect is that the cache is not up-to-date, which means that next time it will rebuild.

Great, thanks! I’ll ignore this unless I see another problem, then. -Gordon.
