NO_MORE_IRP_STACK_LOCATIONS (0x35)
What is this error?
A driver attempted to push more I/O Request Packet stack locations than available. Too many filter drivers are stacked on the I/O path.
Common causes
- too many filter drivers installed
- antivirus + backup + encryption stacked
- minifilter driver misconfiguration
How to fix it
- Reduce the number of stacked filter drivers
- uninstall redundant security/backup software

Bug check 0x00000035 (NO_MORE_IRP_STACK_LOCATIONS) occurs when a driver chain has more filter drivers than the IRP (I/O Request Packet) has stack locations for. Each filter driver (antivirus, backup, encryption, cloud sync) adds a layer to the I/O path. Too many layers exhaust the available stack locations. Common offending combination: antivirus + real-time backup (CrashPlan, Backblaze) + cloud sync (OneDrive, Dropbox) + encryption (BitLocker or third-party) all filtering the same volume. Fixes:
- Reduce stacked I/O filter software — do you really need antivirus + backup + cloud sync + encryption all active?,
- Uninstall redundant backup or sync software,
- Run 'fltmc' from admin command prompt to see all loaded filter drivers,
- Increase IRP stack size via registry: HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters → IRPStackSize DWORD (default 15, increase to 25).
