Hello all, could anyone explain the exact meaning of parameter nproc? Why different values of nproc give so different critical values, i.e. meanL2BB$computeCritval(0.05,nproc=3) [1] 0.9984853 meanL2BB$computeCritval(0.05,nproc=1) [1] 0.4594827 The strucchange-package description gives "integer specifying for which number of processes Brownian motions should b...

...as and so now I need to place ulimits on place. Attempts to use AD domain groups fail. So I'm not sure this is an issue for samba+winbind or for /etc/security/limits.conf and pam. Here's what I have added in limits.conf # -- fix fork bomb issue -- @"Domain Users" soft nproc 20 @"Domain Users" hard nproc 20 And here is what I have in pam.d/common-session session required pam_limits.so -- I'm pretty sure the pam stuff is correct because I was able to set nproc limits on a non-domain user. But I'm wondering if we can se...

Dear all, I found a strange thing with the snow package. This will work: y = matrix(1:4, 2) cl = makeCluster(rep('localhost', 8), type='SOCK') parMM(cl, y, y) This will not: y = matrix(1:4, 2) ncore = system('nproc') parMM(cl, y, y) Error in cut.default(i, breaks) : invalid number of intervals I also tried: cl = makeCluster(rep('localhost', ncore), type='SOCK') cl = makeCluster(rep('localhost', as.integer(ncore)), type='SOCK') no luck. Could anyone please help? Thanks!...

We have CEntos 5.5 on DELL server. Due to more and more databases run on same server sometime processes number read max and cause 'resource temporary unavailable". I plan to change /etc/security/limits.conf value: oracle soft nproc 2047 ==> 4096 Do i need reboot to make it effect? How to test change is effect? Thanks.

...Severity: normal Priority: P2 Component: sshd AssignedTo: openssh-unix-dev at mindrot.org ReportedBy: vasil at dobrich.net Background: debian woody, kernel 2.4.17 The problem is, when you set some resource limits in /etc/security/limits.conf for group X - nproc 20 ( maximum of running user processes - 20 ), and try to log with some user with group X, sshd says 'fork failed - resource temporary unavialable'. There are no other processes running for this user, and as far as i've seen, it makes something like authenticate-set limits-fork()-setuid...

I have removed the 1024 nproc limit in /etc/security/limits.d/90-nproc.conf, and upped the nproc and nofile limits to 16384 and 65535 respectively, both in limits.conf, as well as adding ulimit statements in /etc/init.d/dovecot (belt and suspenders).

I re-wrote the compile script to build klibc (cleaning up how I do it, and how to find the source tarballs). It seems to be compiling fine. I tried several of the commands in usr/utils/static and most one.
