Description
|
The extended accounting system (exacct) can, when assembling interval records
for tasks, record incorrect results for the resource counters. These values
may be extremely large --- of the order of 2^64 --- but this is not always
the case.
This bug has been seen on a multi-CPU machine; I do not believe that it will
happen on a single-CPU system. The bug occurs when wracct(1M) or wracct(2) is
used to request an interval record for a task at the same time that one of
that task's member processes is exiting.
