Hello, we stumbled over some mysterious errors of some applications. An analysis showed that the applications had a filedescriptor #4 opened on [u]/var/sadm/install/.lockfile[/u] Each affected application was running in global zone of Solaris 10u2.
After a long run of discussion and analysis sessions between admins and developer we turned out with the idea this might be an inherited filedescriptor from pkgadd. To test this I've put the command [u]lsof -p $$[/u] into a checkinstall script, build a new package and installed it. And surprise - here is the output of lsof: [pre] COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME sh 7619 noaccess cwd VDIR 32,51 512 5 /var/sadm/install sh 7619 noaccess txt VREG 32,48 95488 2926 /sbin/sh sh 7619 noaccess txt VREG 32,48 41088 21420 /lib/libgen.so.1 sh 7619 noaccess txt VREG 32,48 24996 227407 /usr/lib/locale/en_US.ISO8859-1/en_US.ISO8859-1.so.3 sh 7619 noaccess txt VREG 32,48 1259500 2318 /lib/libc.so.1 sh 7619 noaccess txt VREG 32,48 16856 6082 /platform/sun4u/lib/libc_psr.so.1 sh 7619 noaccess txt VREG 32,48 253456 2185 /lib/ld.so.1 sh 7619 noaccess 0r VCHR 13,2 6815752 /devices/pseudo/mm at 0:null sh 7619 noaccess 1w VCHR 22,0 11534340 /devices/pseudo/sy at 0:tty sh 7619 noaccess 2w VCHR 22,0 11534340 /devices/pseudo/sy at 0:tty [b]sh 7619 noaccess 3r VREG 0 1464583847938 /src/pkg/AKo-Test-5.8.6.pkg sh 7619 noaccess 4u VREG 32,51 128 10 /var/sadm/install/.lockfile sh 7619 noaccess 6r VCHR 13,2 6815752 /devices/pseudo/mm at 0:null sh 7619 noaccess 7w VCHR 22,0 11534340 /devices/pseudo/sy at 0:tty sh 7619 noaccess 19r VREG 32,51 1547 35270 /var/tmp/installGMaq4o/checkinstallIMaq4o[/b][/pre] Is there any reason that filedescriptors 3, 4, 6, 7 and 19 are open during checkinstall run? (numbers vary from time to time) While installing a local zone, postinstall of pkg files to be installed will get an filedescriptor inherited as open on [u]<zonepath>/root/var/sadm/install/.lockfile[/u] Well, in our case it was filedescriptor #3, which put our applications into trouble. If there is no reason for filedescritors >2 beeing open during execution of checkinstall or postinstall (and I'm sure there is none!), then this must be considered as an error!
