tbspaces hangs , why ?

Hi , all I run installation script from packaging tool ( OS System V , release 4 ) An standart input is closed by packaging tool. At installation of the package I run from shell script : tbinit -iy sleep 60 #and right here /usr/informix/bin/tbspaces -c -d my_dbspace -p /dev/informix -o 0 -s 100000 As result of it tbspaces hangs with tbstat -u flag C - waiting for checkpoint. #tbstat -m shows RSAM Version 5.02.UC7X1 -- On-Line (CKPT REQ) -- Up 00:00:23 -- 4784 Kbytes Users address flags pid user tty wait tout locks nreads nwrites 8027ec ------D 6320 root console 0 0 0 3 21 802860 ------D 0 root console 0 0 0 0 0 8028d4 ------F 6321 root 0 0 0 0 0 802948 ------F 6322 root 0 0 0 0 0 8029bc C-B---M 6355 root console 0 0 0 0 3 Also tbinit do not perform checkpoint according to CKPTINTVL 300 in the tbconfig. Online is hangs. What could cause such strange behavior ? If I run in another session tbmode -c then tbspaces goes on , but following after it additional tbspaces also hangs for checkpoint as well. Additional : If I run simple shell script with tbinit -iy and tbspaces -c everything is OK. How do explain this stuff ?! I can't May be DBA's have something to say ?
