2. Operational Issues
2.1 GOCDB data scoping overview
Presentation: File:GocdbScopingHighLevel.pdf
2.2 Top BDII memory issue
A serious memory issue was reported in two GGUS tickets:
[ 76337 ]: "bdii tmpfs fills up and silently fails"
[ 73840 ]: "bdii memory leak?"
The RAMdisk usage of the service increases until the service occupy all the available memory. After that it needs to be restarted.
The BDII versions affected are:
- gLite 3.2.11
- EMI 1.0.0-1
No information about EMI 1.0.1 (Distributed with UMD 1.3), if it is affected or not.
First partial mitigation suggested by developer:
- Configuration patch, comments the following directives:
- #set_flags DB_LOG_INMEMORY
- #set_flags DB_TXN_NOSYNC
- This reduces the memory grow, but does not solve the problem
Mitigation:
- The only workaround for the problem, so far, is to restart the Top-BDII service.
2.3 Survey ongoing
Survey about the request for SLURM support in CREAM. Survey description
- Deadline is tomorrow: Dec 14th.
- Many sites answered (69), probably most of the sites not interested in SLURM did not answer (reasonably).
