...e pweibull function is annoyingly producing NaNs, which nls() refuses to handle. I have put a sample of the code below. Is there a way to prevent these NaNs from interfering, for example a method to catch them? I get the following error when I try to run the code: res.nls <- nls(cumsumcaught ~ Pcatch*Prepens.released*(1-pweibull(distances,k,l)), + start = list(k=1,l=12), trace=T, control = my.control) Error in numericDeriv(form[[3]], names(ind), env) : Missing value or an infinity produced when evaluating the model In addition: Warning messages: 1: NaNs produced in: pweibull(q, shape,...

Hello, I am having a problem with my dovecot-daemon. It is forking one or more (I saw up to perhaps 8 of them) imap processes under my user name. These processes are consuming a lot of CPU time and are not killable: > PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND > 8616 arno 20 0 2900 1600 1204 R 98 0.2 1196:38 imap Stopping dovecot does not quit these

I'm running a few servers sitting on top of a NetAPP file server ? everything runs great, but periodically I'm getting: nfs_getpages: error 13 vm_fault: pager read error, pid 11355 (https) errors on my screen ? not always same pid ? the annoying part is that it seems to always affect the same jail that is running .. if I shutdown all jails on that physical server, everything shuts down
