Dear All, One of our WN is doing this pretty regularly since March 3 2009: Aug 25 10:39:49 bse06 kernel: glite-brokerinf[17689]: segfault at 0000000000000000 rip 00000032adc8ffa6 rsp 0000007fbfffe3a0 error 4 No others are doing that. Can anyone suggest if this matters, like what might be bad fallout from that, &/or how to debug? Or is it harmless? There's nothing in tb-support/lcg-rollout archives mentioning glite-brokerinf. Jobs seem ok on the WN, but zeus is having some lcg-cr upload problems, at least known on that WN, so checking it over. OS is SL4.6 2.6.9-67.0.7.ELsmp x86_64 (for gpfs cluster compat) WN all have installed glite-wms-brokerinfo-access-3.1.3-1.slc4.x86_64 But only one doing the segfault. Many thanks for enlightenment wl
