Hi Groggy (whom I didn't contact for too long a time), everybody,
following the advice on your page, I include the FreeBSD list, even though I'm not subscribed there (hoping it will allow me to post) - so please, whoever replies, could you please cc: me directly? Of course, I tried Google, but I didn't find any answers to my question. For some long, unknown time, the MySQL code contains a variable "net_retry_count" which is by default set to 10 (ten) for all platforms, but to 1000000 (1 million) for FreeBSD (during configure phase). The source code comment about this variable reads If a read on a communication port is interrupted, retry this many times before giving up. The documentation (manual) has this sentence in addition: This value should be set quite high on FreeBSD because internal interrupts are sent to all threads. I read that as "On FreeBSD, a thread may receive many more interrupts than on other platforms, so an operation which may take some time (like network I/O) may be interrupted much more often than on other platforms, and hence the retry count should be higher." I trust that this comment was valid at the time it was written - is it still true for current versions of FreeBSD, or did things change?
