<br>I think I figured out why Cog some times terminates when downloading large files on OSX;<br>
An oversleep which is interrupted can be returned as a t_time struct with tv_sec -1 and tv_nsec close to 999999999.<br>
<br>
The while check is<br>
nanosleep (&naptime, &naptime) == -1 && naptime.tv_sec > 0 1|| naptime.tv_nsec > MINSLEEPNS<br>
<br>
or so, so when an interrupt is encountered which has tv_sec = -1, you will get the invalid argument error.<br>
<br>
rewriting it to<br>
naptime.tvsec > -1 && naptime.tv_nsec > MINSLEEPNS && nanosleep(&naptime, &naptime) == -1<br>

I no longer had crashes in 99% of hte cases when evaluating the following test:<br>
