Hi all,
we are facing many SOLR errors, both on our search and statistics core. One
recurring error relates to auto-commit giving IOException.
In the tlog directory many tlogs remain indicating that commit fails.
Is there a way to repair our statistics core?
best wishes,

[this may be caused by lack of enough unfragmented virtual address space or
too restrictive virtual memory limits enforced by the operating system,
preventing us to map a chunk of 309036569 bytes. Please review 'ulimit -v',
'ulimit -m' (both should return 'unlimited'), and 'sysctl
