tmux 不能正常啟動 - Linux

大家好，

上週的某天開始，我在一台Ubuntu 14.04 Server上的tmux 就無法新增window/session

而只要我在輸入： `tmux` ，螢幕就會跳出62;9;c

另外若用root帳號，開tmux是成功的，而一般使用者底下則都會失敗，

並且有一樣詭異的62;9;c 的錯誤訊息。

我嘗試google，但是找到的解法都沒用。

另一個可能的方向，是permission的問題，所以我在bash輸入：

`strace -f -e trace=file tmux`

並且得到以下的log：

```

```

我猜測是最後那幾個動作導致tmux啟動失敗，

可惜在child process中strace沒有自動解出指標的filepath。

（我是不是漏了什麼參數呢？）

請問各位還有沒有什麼建議呢？

ps. 我很想重開機，但是這是多人共用的server，所以目前無法重開...
