Hi altogether!
 There are several points to take into account in respect to your problems.
 1) On several computer systems there were set certain limits for users
 especially if
 many people are working on such systems because the users have to divide the
 available
 resources. You can examine this possibility with "quota -v".
 2) If you are working with NQS (Network Queuing System) you have to examine
 if there are some kinds of limitations.
 3) Maybe you have some limitations for one file or one job setting with the
 order
 "limit".
 Generally, the error message: "Erroneous write. write -1 instead of
 50250000"
 indicates a disk space problem and no memory problem. "write -1" means
 that the
 Computer could not write to a certain file since there are some limitations or
 your
 computer system has essentially not enough physical disk space. So your swap
 space of
 about 2GB will be useless concerning your actual problem.
 Frequency calculations and any kind of high level calculations such as QCISD or
 MP4
 need a lot of disk space. For example your frequency calculation needs
 less than 200MB memory space for every pass but your disk space requirements
 will be
 possibly 30GB or more.
 Increase your disk space or reduce your level of calculations or your basis set
 and
 all your problems (no, of course only this problem) will disappear.
