[oe] bitbake freeze :(

[Steffen Sledz]

Since a few days i see this crazy behavior. Sometimes bitbake freezes (everytime at the same stages if it freezes) when building a target (e.g. with "bitbake drapptempl"). top tells me that a "make all" process is running and consuming all resources of one cpu. The last lines of an strace show always something like this:

...
5909  stat64(".deps/drapptempl-main.Po", {st_mode=S_IFREG|0644, st_size=8, ...}) = 0
5909  lstat64(".deps/drapptempl-main.Tpo", {st_mode=S_IFREG|0644, st_size=32496, ...}) = 0
5909  lstat64(".deps/drapptempl-main.Po", {st_mode=S_IFREG|0644, st_size=8, ...}) = 0
5909  rename(".deps/drapptempl-main.Tpo", ".deps/drapptempl-main.Po") = 0
5909  close(0)                          = 0
5909  close(1)                          = 0
5909  close(2)                          = 0
5909  exit_group(0)                     = ?
5898  <... wait4 resumed> [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 5909
5898  --- SIGCHLD (Child exited) @ 0 (0) ---
5898  sigreturn()                       = ? (mask now [])
5898  rt_sigprocmask(SIG_BLOCK, [HUP INT QUIT TERM XCPU], NULL, 8) = 0
5898  rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
5898  stat64("drapptempl-main.o", {st_mode=S_IFREG|0644, st_size=107848, ...}) = 0

The recipe for the freezing task looks like this:

 DESCRIPTION = "HydraIP Linux Application Template"
 SECTION = "console/utils"
 PRIORITY = "optional"
 DEPENDS = "libdrhip"

 #SRCREV = "1390"
 SRCREV = "${AUTOREV}" 
 PR = "r1"

 SRC_URI="svn://something.else/repos/HydraIP/trunk/LINUX;module=drapptempl;proto=https"

 PV = "svnr${SRCREV}"
 S = "${WORKDIR}/drapptempl"

 EXTRA_OECONF = "--with-libdrhip-path=${STAGING_DIR_TARGET}"

 inherit autotools

Any idea what's going wrong here? Or how to isolate the problem?
