Error description

  • When building in an IBM Rational ClearCase 8.0.1 host running
    Microsoft Windows 2003 server, the following errors may occur
    during builds if kernel memory is scarce:
    
    fatal error C1085: Cannot write precompiled header file:
    '../Release\myfiles.pch': The supplied user buffer is not valid
    for the requested operation.
    
    The following error appears in the MVFS log:
    mvfs: Error: {4 pid/tid x/y} mvfs_nt2vfs_rdwr_workitem: Error
    0xC00000E8 on completing a IRP_MJ_WRITE with the file
    0xdeadbeef.
    
    Error 0xC00000E8 is the NTSTATUS code for "invalid user buffer"
    
    In this case, the system was trying to do a write of a 73MB
    buffer. Filesystem IO requests lock the user buffer before
    sending it down. This lock was failing, but the failure was not
    being caught. Sending the "unlocked" user buffer to the OS for
    filesystem IO caused the "invalid user buffer" response.
