請幫忙診斷netstat -m的輸出

壞蛋

netstat -m輸出情況如下，請高手診斷一下可能是哪方面的問題，主機(jī)安裝SCO UNIX 5.05，通過中間件與遠(yuǎn)端主機(jī)通訊，當(dāng)時本主機(jī)網(wǎng)絡(luò)已經(jīng)癱瘓，除了ping本機(jī)以外，ping不通網(wǎng)關(guān)、同網(wǎng)段其它主機(jī)，其它主機(jī)網(wǎng)絡(luò)正常。其它主機(jī)的應(yīng)用情況是相同的。
另外，請各位高手指點一下UNIX系統(tǒng)核心參數(shù)調(diào)整的原則及心得吧，我假設(shè)現(xiàn)在是流資源不足，機(jī)器是P4,512M內(nèi)存的PC，應(yīng)該如何調(diào)整？
