Note: This behavior has been fixed in Junos 12.3R12-S2, Junos 12.3R13, Junos 14.1X53-D40, Junos 15.1R4 Change the file access permissions for /jail/var/tmp as follows:
root@host:RE:0% cd /jail/var root@host:RE:0% ls -lrt total 12 drwxrwxrwx 2 root wheel 512 Oct 6 21:04 run drwxrwxrwx 2 root wheel 512 Oct 8 01:42 etc drwxrwxrwt 3 root wheel 512 Oct 8 20:17 tmp root@host:RE:0% chmod 777 tmp root@host:RE:0% ls -lrt total 12 drwxrwxrwx 2 root wheel 512 Oct 6 21:04 run drwxrwxrwx 2 root wheel 512 Oct 8 01:42 etc drwxrwxrwx 3 root wheel 512 Oct 8 20:17 tmp
