Hi,
On AIX 5.3 (20CPU/96GB), the cost of process restart is very expensive. These
patches improve performance by avoiding unnecessary exit()
call.
avoid_shut_down_if_no_input.patch:
Everytime our Alteon opens a socket for the health check, it kills a
process. Just because it don't send any data. The problem can be
easily reproduce with a telnet connection.
cyrus-imapd-2.3.16-ignore_ECONNABORTED.patch:
If the connection is closed by the client, the process gets an ECONNABORTED
error (Connection aborted POSIX.1). This new patch catches this error.
Best regards,
