# 1726 Cannot Mix 3.26 Clients with 3.27 Database Servers Without Causing Database Server Crash

---

C/S Mode (TCP/IP) When using components OR dbsys:

3.26 client editing or appending blob/memo data to a table on a 3.27 server - both client and server crash.

3.27 Client editing or appending blob/memo data to a table on a 3.26 server - no crash, but data is garbaged and hugely inflated. A 500K blob typically inflates to 20/50 MB

Both these problems happen 100% of the time.
