gridsite causes WMS delegation problems
see details in GGUS #95559 GGUS #95646 GGUS #95882
The latest release of gridsite (1.7.26 in EMI-2 and 2.1.0-1 in EMI-3) doesn't allow the '-' character to be used in the proxies delegation when submitting through a WMS server.
This causes many intermittent errors in the delegation of proxies on both EMI-2 and EMI-3 WMS servers:
Warning - Unable to delegate the credential to the endpoint: https://wms014.cnaf.infn.it:7443/glite_wms_wmproxy_server Unknown Soap fault Method: Soap Error
and in the wmproxy.log there is the following error message:
09 Jul, 15:35:33 -I- PID: 982 - "wmpgsoapoperations::delegationns__putProxy": ------------------------------- Fault description -------------------------------- 09 Jul, 15:35:33 -I- PID: 982 - "wmpgsoapoperations::delegationns__putProxy": Method: putProxy 09 Jul, 15:35:33 -I- PID: 982 - "wmpgsoapoperations::delegationns__putProxy": Code: 60 09 Jul, 15:35:33 -I- PID: 982 - "wmpgsoapoperations::delegationns__putProxy": Description: Proxy exception: Unable to store client Proxy 09 Jul, 15:35:33 -D- PID: 982 - "wmpgsoapoperations::delegationns__putProxy": Stack: 09 Jul, 15:35:33 -D- PID: 982 - "wmpgsoapoperations::delegationns__putProxy": ProxyOperationException: Proxy exception: Unable to store client Proxy at putProxy()[../../../src/security/delegation.cpp:176] at putProxy()[../../../src/security/delegation.cpp:153] at putProxy()[../../../src/server/operations.cpp:605] 09 Jul, 15:35:33 -I- PID: 982 - "wmpgsoapoperations::delegationns__putProxy": ---------------------------------------------------------------------------------- 09 Jul, 15:35:33 -D- PID: 982 - "wmpgsoapoperations::delegationns__putProxy": putProxy operation completed
The developers are preapring the fix. In the meantime, as a temporary workaround, downgrade to the previous version of gridsite:
- On a WMS: yum downgrade gridsite gridsite-libs
- on an UI: yum downgrade gridsite-commands gridsite-libs
StoRM 1.11.1 performance problems
see details in 95700
In the latest STORM EMI-3/SL6 version it was found several load issues: in particular a lot of thread was generated, reaching the limit of 1024 in /etc/security/limits.conf . Even increasing the limit, the number of threads increase as well, and the service performance is very low. The issue is under investigation.
It seems there are two problems. The main problem is related to the interaction with mysql (slow queries make the latency for transfer operations steadily increase. Because of the latency, the StoRM gets a lot of abort requests. And then the second problem: every abort command creates a new thread that keeps alive until garbage collection. The fix for both problems is under testing.
