<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">We do the real task when sstate cache fetch fails and we are trying to identify the reason why bitbake returns 1 (which happens when error count != 0) even when
real task succeeds. We see that Bitbake returns 1 in this case which causes random build failure even when the real task was performed successfully.
