1. Middleware releases and staged rollout

1.2 Staged Rollout (Mario)

1.2.1 gLite 3.2

1.2.2 UMD1

2. Operational Issues

2.1 GOCDB data scoping overview

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.
